Description
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
A vulnerability was found in polkit. When authentication is performed by a non-root user to perform an administrative task, the authentication is temporarily cached in such a way that a local attacker could impersonate the authorized process, thus gaining access to elevated privileges.
